Subject [jira] [Commented] (YARN-4350) TestDistributedShell fails
Date Sat, 14 Nov 2015 00:35:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-4350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15004969#comment-15004969
] 

Sangjin Lee commented on YARN-4350:
-----------------------------------

As I mentioned in YARN-2859, I'm not sure if that is the reason for test timeouts here. Using
":0" should have the same effect of finding an available ephemeral port if I'm not mistaken.
Also, all other daemons in the mini YARN cluster are doing that without issues.

Also, please note that the test works just fine on trunk.

> Currently TestDistributedShell does not pass on the feature-YARN-2928 branch. There seem
to be 2 distinct issues.
> (1) testDSShellWithoutDomainV2* tests fail sporadically
> These test fail more often than not if tested by themselves:
> {noformat}
> testDSShellWithoutDomainV2DefaultFlow(org.apache.hadoop.yarn.applications.distributedshell.TestDistributedShell)
 Time elapsed: 30.998 sec  <<< FAILURE!
> java.lang.AssertionError: Application created event should be published atleast once
expected:<1> but was:<0>

> {noformat}
> They start happening after YARN-4129. I suspect this might have to do with some timing
issue.
> (2) the whole test times out
> If you run the whole TestDistributedShell test, it times out without fail. This may or
may not have to do with the port change introduced by YARN-2859 (just a hunch).
